Those "dirtied" wheels are very nicely replicated Dave. I'm close to the dirtying stage on my Brisfit and will try your technique for certain!
Cheers,

Thanks Guys,

The tyres: yes there were lots of colour tones and variations, just looking at contemporary photographs.
I have tried to make the tyres look the same tone as seen in the photograph, with the mud splashed around the rim and the hub.
Looking at actual tyres in museums on the few preserved WW1 machines, I am thinking of the Halberstadt in the Brussels Air Museum which is one example , the colour certainly looks very dark grey if not black.
Of course other photos show very light coloured rubber, so just try to copy your reference pictures I suppose.

Ernie- the control cables on my model are currently a brown colour from the monofilament chameleon fishing line.
My guess is that they will be a weathered steel, therefore appearing a metallic grey after some weathering. I wll try some sample colours before deciding on what to do with them.
Ray's datafile shows the Munich Rumpler with this greyish colour.

Meanwhile some work is happening on the Mercedes engine, stay tuned...

So, the Mercedes is being assembled...

Alclad aluminium is the crankcase colour with the cylinders painted with Tamiya enamel semi-matt black, as well as the induction manifold. On this aircraft there was no asbestos lagging evident on the photos so it was left in the factory black finish.

The exhaust was drilled out and then painted in Mr Color Burnt Iron and drybrushed with MrColor Stainless. I am quite pleased with the final finish of the exhaust as this is a difficult finish to get looking correct. I got the technique from the fabulous new Guide to building WNW aircraft volume 1. I would heartily recommend this guide, with some great builds inside.

Now building up the courage to tackle the plugs, leads and magneto connections.

I simulated the burnt oil on the crankcase by several layers of AK Fuel Stains, painted on carefully until I acheived a look I was happy with.

Most of this will be hidden when installed in the airframe.

Dave, the engine is looking really good. I think you've done brilliantly with
the staining on the crankcase.  It's looking absolutely right.  Looking forward
to the next progress photos.

Cheers,
Ernie :)

Dave,
   The oil staining on the crankcase is very realistically done. What is and can you provide more info on the product, "AK Fuel Stains" that you used. Looking like another winner!
Cheers,
 Lance

Quick update....spinner and Wolff propeller.....

The spinner was presprayed with Alclad aluminium then sprayed with a custom mixed mauve colour. I then took a toothpick and took a few very small chips out of the spinner to leave the aluminium underneath. This is a very subtle effect as photographs of the actual machine show very little or no wear.

Prop was Tamiya XF-60 then mahogany colour pencils for the dark laminate plus wood grain, followed by Tamiya clear with one drop clear orange to two drops tamiya clear yellow.

Several layers of this varnish applied before the Wolff decals then final finish of Tamiya clear.

Re the engine staining. I used about 3 light coats brushed on so as to pool in a couple of areas. The AK Interactive Fuel Stains is a thin enamel brown varnish so you will have to leave it a couple of days to harden up. I tried to get the effect I have seen on several period engines in museums around the world. Interestingly, if you have ever dabbled in radio control aircraft, you get the same staining on the glo-plug engines after a few hours of use, once the castor oil has burned onto the hot metal of the crankcase.

Hope this answers your questions.

Once again thanks for your comments and interest everybody.

Fuselage close up is next

I have mixed up the WNW recipe for the underside blue....again Tamiya colours were used....it looks pretty pale in colour.
Sprayed the undercarriage legs shown and undersides of the wings now to see the effective colour.
Base colour was vallejo gray primer.

Disaster struck when I carelessly dropped the undercarriage wing axel and broke off one of the axel ends.
Drat!

Have drilled out the ends of the axel now to 0.5 mm and inserted brass wire ca'ed to improve the strength.
I'll build up the broken section using some tubing later before mounting the wheels properly.



Some more fuel stains applied to the wing axel,but maybe some more will be added later towards the end of the build.

Good save on the undercarriage, Dave.  The brass wire should be even
better than new.

Cheers,
Ernie :)

She's coming together really well Dave, the exhaust tends to dominate the whole plane at the moment, looking forward to further updates.
